What does ADST mean in DEVELOPMENT

Assay Development and Screening Technology (ADST) is a process used in drug discovery and development to identify active ingredients or molecules that can interact with a target receptor. ADST typically involves the use of high-throughput screening tools, such as cell-based assays, protein crystallography and biophysical techniques, to quickly identify compounds with desired activities.

During ADST, scientists rapidly screen large numbers of compounds for their biological activity. The screening process includes the identification of hit compounds from assay plates or libraries of compounds, optimization of hits into leads with higher affinity for the target molecule, and selection of potential drug candidates for further development.

After ADST, additional steps may be taken to optimize lead molecules towards drugs identified through mode-of-action studies, pharmacokinetic testing in preclinical models, efficacy studies in animal models, physicochemical characterization (for example to assess solubility), formulation design and toxicological assessment.

ADST is used primarily by pharmaceutical companies involved in drug discovery research who are searching for new treatments for diseases. It is also used by academic researchers working on drug design projects related to biology or chemistry.

Technologies commonly used in ADST include cell-based assays employing both human cells cultures as well as animal cells; computer modeling techniques; genetic engineering approaches; spectroscopic methods; protein crystallography; molecular interaction mapping (MIM); high throughput screening (HTS); surface plasmon resonance (SPR); mass spectrometry (MS); European Bioinformatics Institute’s ChemSpider database; ELISA assays; qPCR assays; Proteome Profiler arrays; peptide synthesis using solid phase synthesis; X-ray diffraction experiments with crystallized proteins structure determination.

By using a combination of these technologies - including but not limited to cell-based assays, protein crystallography - researchers can quickly determine which molecules have desired activities as potential drug candidates. These activities could be anything from binding to particular biological targets through modification of gene expression or inhibition/activation of enzymes on metabolic pathways resulting in the desired therapeutic effect.

ADST involves performing numerous tests in rapid succession which could potentially expose test subjects or sensitive environments to unnecessary risk if proper safety measures are not taken. Additionally, it is important that the data generated by these tests are accurate so that effective decisions can be made about which molecules should be progressed further into development stages.

The goal of an ADST program is to identify compounds with desirable properties like target specificity or potency so that they can be progressed further along into research pipelines leading potentially to new medicines for various diseases. As such, depending on the parameters set at the outset results will range from Hit identification through Lead optimization all the way up to preclinical/clinical candidate selection.

This depends largely on what kind of testing protocols have been established prior to beginning the project as well as how many different compounds need to be evaluated during screening sessions. Parameters like these will affect time frames ranging from weeks up to months.
